Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Contents

Dependencies

Requires Node.js 10.x or later. No other dependencies to conflict with your app.

Installing With npm

npm install resurfaceio-logger --save

Logging From Express Middleware

After installing the module, add a HttpLoggerForExpress instance to your app, after any body parsers in use.

const express = require('express');
const app = express();

// add body parsers

const resurfaceio = require('resurfaceio-logger');
resurfaceio.HttpLoggerForExpress.add(app, {
    url: 'http://localhost:4001/message', 
    rules: 'include debug'
});

// define routes

Logging From Koa Middleware

After installing the module, add a HttpLoggerForKoa instance to your app, after any body parsers in use.

const Koa = require('koa');
const app = new Koa();

// add body parsers

const resurfaceio = require('resurfaceio-logger');
resurfaceio.HttpLoggerForKoa.add(app, {
    url: 'http://localhost:4001/message', 
    rules: 'include debug'
});

Logging From Apollo Server on Express

After installing the module, add a HttpLoggerForExpress instance before calling applyMiddleware.

const app = express();

const resurfaceio = require('resurfaceio-logger');
resurfaceio.HttpLoggerForExpress.add(app, {
    url: 'http://localhost:4001/message', 
    rules: 'include debug'
});

const server = new ApolloServer({ ... });

server.applyMiddleware({ app });

Logging From Specific Express Routes

After installing the module, create a logger and call it from the routes of interest.

const express = require('express');
const app = express();

const resurfaceio = require('resurfaceio-logger');
const logger = new resurfaceio.HttpLogger({
    url: 'http://localhost:4001/message',
    rules: 'include debug'
});

app.get('/', function (request, response) {
    response.render('pages/index', function (e, html) {
        response.status(200).send(html);
        resurfaceio.HttpMessage.send(logger, request, response, html);
    });
});

Logging With API

Loggers can be directly integrated into your application using our API. This requires the most effort compared with the options described above, but also offers the greatest flexibility and control.

API documentation

Protecting User Privacy

Loggers always have an active set of rules that control what data is logged and how sensitive data is masked. All of the examples above apply a predefined set of rules (include debug), but logging rules are easily customized to meet the needs of any application.
